COMBINED WATER-COOLER AND REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 342,330, dated May25,1886.

Application filed August 24, 1885.

To aZZ whom it may concern:

Be it known that I, JOSIAH D. COLONY, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Combined ater Coolers and Refrigerators, of which thefollowing is a specification.

The object of myinvention is to so combine a refrigeratingchamber with awater-cooler as to obtain a large air-cooling surface and insure aneffective circulation of the air through the refrigeratingchamber. Thisobject I attain in the manner which I will now proceed to describe,reference being had to the accompanying drawings, in which- Figure l isa vertical section of my improved water-cooler and refrigerator; Fig. 2,a transverse section of the same; Fig. 3, a sectional plan on the line 12, Fig. 1; and Fig. 4, a sectional plan on the line 3 4, Fi l.

A is the outer casing of the structure, which is made double, as usual,and is packed with nouconducting material, and between this casing andthe casing B of the water-reservoir and refrigerating-chamberiutervenesaspace, which is divided by a central partition, a, into outer and innerpassages, 11 d, communicating with each other at the upper end over thetop of the partition (1., the inner passage, (1, communicating with thelower portion of the refrigerating-chamber D, and said chamber, at apoint some distance above the bottom, communicating through pipes orpassages f with the outer passage, b. By this means a circulation isinduced in the provision-chamber D, the warm air escaping from the samethrough the passage f, and rising in the outer passage, 1), until itreaches the top of the same, where it enters the passage cl, and iscaused to descend therein by reason of its being cooled by contact withthe casing B of the ice-water reservoir F, the cool air entering thebottom of the provision-chamber through suitable perforations, g.

The provision-chamber D has a dome-shaped top, G, connected to thecasing B at its lower edge, this top being less in diameter than thecasing, so that it is surrounded by water in the annular space 71, andthereby forms an in Serial No. 175,184. (No model.)

ternal refrigerating-surface, thus causing in the upper port-ion of therefrigerating-chamber a secondary circulatiou--such as indicated by thearrows 2-and this circulation being independent of that in the lowerportion of the refrigeratingchamber, which is indicated by the arrows 1.

The provision-ehamber is closed in front by a door, H, preferablyforming part of the easing of the structure, and packed like the same torender it nonconducting.

The lower portion of the structure is eX- panded in diameter, so as toincrease the capacity of the provision-chamber without unduly increasingthe diameter of the ice-Water reservoir.

The structure above described combines with a water-cooler arefrigerator of moderate capacity, which can be constructed more cheaplythan the refrigerators now in use.

I claim as myinvention- 1. The combination of the outer casing, A, withan internal casing inclosing the water and ice reservoirs andprovisionchamber, and separated from the outer casing by a space formingair-circulating chambers communicating with said provision-chamber, asspecified.

2. The combination of the outer casing, the inner casing inclosing thewater and ice reser voirs and provision-chamber, the air-passagesbetween the inner and outer casings, and a provisionchamber having acommunication, f, with said air-passages, and a chamber above thiscommunication, all substantiallyas specified.

3. The combination of the provision-chain her, the water-reservoiraround the same, and the ice-reservoir above it, with the casingcontracted at the ice-reservoir, but expanded below the same, allsubstantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOSIAH D. COLONY.
